Abstract
A method for producing a solid antifoaming agent comprising the following steps: providing an alkaline solution; adding an oil to the above alkaline solution to produce a saponification reaction; adding a liquid antifoaming agent; and putting aside the mixture containing the above alkaline solution, the oil and the liquid antifoaming agent to form the solid antifoaming agent. The ingredients of the solid antifoaming agent according to the present invention include 5˜40 weight percent vegetable oil, a 20˜40 weight percent sodium hydroxide solution and a 30˜60 weight percent liquid antifoaming agent.
Claims24
A solid antifoaming agent manufacturing method comprising the following steps:
- preparing an alkaline solution;
- adding an oil to said alkaline solution to produce a first mixture with a saponification reaction;
- adding a liquid antifoaming agent to said first mixture to produce a second mixture;
- adding an agar to said second mixture containing said alkaline solution, said oil and said liquid antifoaming agent to produce a third mixture;
- and
- putting aside said third mixture containing said alkaline solution, said oil, said liquid antifoaming agent and said agar to form said solid antifoaming agent;
- wherein said liquid antifoaming agent adding step includes adding 30˜60 weight percent liquid antifoaming agent based on weight of total compositions of the solid antifoaming agent.
A solid antifoaming agent manufacturing method comprising the following steps:
- preparing an alkaline solution;
- adding an oil to said alkaline solution to produce a first mixture with a saponification reaction;
- adding a liquid antifoaming agent to said first mixture to produce a second mixture;
- shortening the reaction time of said second mixture containing said alkaline solution, said oil and said liquid antifoaming agent by adding an agar and powdered activated carbon (PAC) to said second mixture to produce a fourth mixture;
- and
- putting aside said fourth mixture containing said alkaline solution, said oil, said liquid antifoaming agent, said agar and said powdered activated carbon (PAC) to form said solid antifoaming agent;
- wherein said liquid antifoaming agent adding step includes adding 30˜60 weight percent liquid antifoaming agent based on weight of total compositions of the solid antifoaming agent.
